820-3115 1/4 fan spin
Going through the rails, everything above pp5v_s5_LDO is stable, PP5v_s5_LDO jumps a bit when the fan pulses, from 4.89vto 5v. Every voltage below that pulses. Everything appears to be trying to come on. Is there a standard way of attacking 1/4 fan spin?- mooserov

820-3115 pp3v3_s0 shorted.
Board reads 0.005 short to ground in diode mode 4.99 ohms in resistance mode. If I inject voltage, it draws a hair over 1 amp, but nothing gets hot. CPU gets warm. Any pointers?- mooserov
